Make cusp::complex compatible with thrust in openmp mode

[GoogleCodeExporter]

I'm planning on doing the following changes to make complex compatible with 
thrust in openmp mode.

It checks for the thrust backend and then defines things appropriately. I just 
need to complete the missing functions.

Any objections?
